# Railway corridors [`tsm_railcorridors`]
|
||||
MineClone 2 adaption. NO TREASURER SUPPORT!
|
||||
|
||||
* Current version 0.11.0
|
||||
* Current version 0.12.0
|
||||
|
||||
Minetest mod for adding underground corridors with rails and wood constructions with
|
||||
a few treasure chests now and then. Optional Treasurer support is available for adding
|
||||
treasures from various mods.
|
||||
Cobwebs are added if the `mobs_monster` mod is found.
|
||||
|
||||
Use the advanced settings to finetune the railway corridors.
